Abstract

The present invention relates to an improved container for food and non-food products. The container utilizes a novel paperboard barrier laminate structure which maintains an isolated gas environment in the container. The laminate makes use of high strength, heat-resistant and caulking polymer layers which prevent pinholes, cuts, or cracking of the barrier layers during blank conversion, package formation, and package distribution. In addition, the novel polymer resin layers act to caulk the seams and channels present in the carton providing a sealed leak free container.
The invention provides an oxygen barrier laminate structure for producing an oxygen impermeable leak free container comprising:
  • (a) a mechanically stable structural substrate (12) having an inner and an outer surface;
  • (b) an outer layer (10) of a heat-sealable low density polyethylene polymer coated on said outer surface of said mechanically stable structural substrate;
  • (c) a polymer layer (14) which exhibits high strength, abuse resistance and toughness in combination with an oxygen barrier layer; and
  • (d) an inner product contact layer of low density polyethylene polymer which is heat-sealable, with the outer layer of low density polyethylene polymer (22) of the laminate, on conventional extrusion equipment at temperatures ranging from 250°F. to 500°F.
